Y '0 all whom it may concezm.

Be it known that I, Mnmu'rr it". Eins- BOURKE, a citizen of United States, residing at Wisconsin Rapids, in the county of 5 Wood, State of lViscons-in, have invented certain new and useful Improvements in Self-Locking Hinges; and I do hereby declare the following to he a full, clear, and exact description of the invention, such as '10 Will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in door hinges.

One object of the invention is to provide a hinge which is self looking to hold the door closed or opened, and at intermediate points.

Another object of the invention is to pro vide a hinge of this character wherein the locking means can be thrown out of operation when it is not desired to use same.

A further object is to provide a. hinge of this character in Which the pintle forms a part of the locking means and has means for adjusting the locking means into and. out of operative position, and is constructed. in such manner that it will not rotate when the door is being opened or closed.

Other o jects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing, Figure 1 is an elevation of a hinge made in accordance With the invention.

Figure 2 is a perspective view of one leaf of the hinge.

Figure 3 is a perspective view of the other leaf of the hinge. Figure 4 is a perspective view of the pin tle removed from the hinge.

Refeaing particulaiiy to the accompany ing drawing 10 and 11 represents the leaves of the hinge, the former having; tn

receiving ears 12 which align with. t tle receiving cars 13 of the otherlea' upper face of the lower of l is formed with a pair ups mulls ing and diametrically opposite t."

lugs 14. The bores for all of the cylindrical with exception of the ear of the leai 10, "which is square in section.

Disposed the lon itudinall throu 'h to a ' wer per tion of which has secured thereon a collar 16, provided with I in its lower face for t e reception or the lugs of the lower pintle of 1i. circling pintle hett c he collar 6% the upper ear of the leaf 11, is a coil spring I' 18, the same serving to force collar into engagement with the power pintle The upper portion of the pintle' is sq are. in cross section and fits snugly within. h: re of the upper pintle 12,. with the result tl it the pintle held. against rotation W leaf i1 is swung thereon.

@utwardly of the squared portion, the pic-- tle is threaded and'receives thereon an in- 79 ternally threaded sleeve or nut 19. l p n rotation of this sleeve, in one direction. the; pintle will he moved longitudinally through the ears to move the coil r 16 upwardly oiit of engagement with the ear l3 whereby the leaves may he readily moved in the mem new of an ordinary Upon of too sleeve in the oppc collar Will be per. to :1: influence of the s 5.8, with the result that the lugs engage in notches of the colleen the door is swung to. tion the logs of the ea of the colli and force the collar and pi upward; a ainst the tension of the spin when the lugs have reached the next notches the spring will force the collar down to receive the lugs in its notches. The door h thus so he held in half open position. i urthei sieve-- mentin the same direction 1 ll lugs of the 13 to the collar and hold the position. The same tl'iing the door d i) i the lugs r' n,

below the lower end of the ear and into the lower ear 12, of the leaf 10. Disposed in the upper ear 13 is a shorter sleeve 12 which extends above the ear and into the lower portion of the upper ear 12. By this construction the pintle 15 remains stationary While the ears together with the sleeves rotate on the pintle.

.What is claimed is- 1. A hinge comprising a pair of leaves having aligning ears, a springpressed pintle disposed through the aligning ears and held against rotation by one of said ears,

means on the pintle cooperating with means on'one of the ears of the other leaf to hold the leaves in different positions, and means on the pintle for adjusting the first-named and for releasing the pintle from the holding ear.

2! A hinge comprising a pair of lea es having align ng ears, one of the ears of one leaf having a bore angular in cross section,

w vre to one of the ears of the other leafhaving lug a pintle disposed through the aligning 5e and having an angular portion fitted in the angular bore of said ear, a notched collar fixed on the pintle for the reception pi the said ear, a nut on one of the lugs of the intle for movin the intle b i eg ons longitudinally through the ears to disengage the collar from the lug carrying ear, and a spring on the pintle hearing against the collar and one of the ears of the hinge to urge the collar into engagement with the lug carrying ear.

3. A hinge comprising a pair of leaves having aligning ears, one of the ears of one of the leaves having an angular bore, a pintle disposed through the ears of the leaves and having an angular portion engaged in the angular hore, inter-engaging means on the pintle and one oi the ears of the other leaf for holding the said other leaf at ditlerent pivotal angles with respect to the first leaf. resilient means for simul taneously holding the interengaging means in engaged position and. the angular portion of the pintle in the angular bore, and means on the piutle for adjusting the pintle longitudinally through the ears and for releasing the angular portion from the augular bore.
